Standard plaster resurfacing typically ranges from $4,000-$7,000 for average-sized pools, depending on prep work needed and access challenges. Aggregate finishes cost more—usually $6,000-$12,000—but last significantly longer and resist staining better in Florida’s environment. The investment often pays off through reduced maintenance and longer service life. Additional costs can include structural repairs found during prep, tile replacement, or equipment updates. Reputable contractors provide detailed estimates after inspection so you know exactly what you’re paying for before work begins.
